Familiarity: I've put it through the wringer
Fit: True to size
Unusual review for me. I was looking for the warmest jacket I could find with literally some of the best cold weather climbing jackets hanging in my gear room now. That included both the Arcteryx Kappa and a Fission SL. The list got one more this winter with the Fission SV. I ordered up new versions of each from BC. Tried them all on and kept the SV. The others went back...nothing new theere from what I already had. A life style new to me, but for the last 6 months I've been getting up just prior to dawn, rain, shine or snow to feed livestock for the last 6 months. One of the coldest winters on record here. The Kappa, a trusted friend for winter climbing in the Alps and Canada wasn't warm enough. The Fission SL, the "go to" hard core winter climbing coat, wasn't up to the task when the wind started blowing @ -25F. Mind you both Arcteryx jackets really good cold weather pieces! But this is an honest comparison made by wearing all three day after day of multiple sub zero weeks this winter. The SV is slightly longer, sheds wind much better than the other two and because of both the length and wind resistance, it is noticeably warmer. The double chest pockets are handier if required. I now know why you see this jacket on a lot of full time ski instructors in the Rocky Mtn States. Not seen a warmer jacket that can take a real beating (day in and day out on the ski hill or in the barn) and still do the job just as well at the end of the Season as the beginning. If you really need a cold weather jacket the SV is worth the extra price compared to the Kappa for warmth IMO. Although feature to feature the Kappa is a better buy if it is warm enough for you. The Fission SL is a great climbing jacket for warmth and weight. But I find it hard to justify the price when compared to the other two. For a climbing parka and really cold dry occasions (think of missing the Tram mid winter on the Midi) my impression is you can do better for warmth and weight (short of snow cave living) by going to one of the better down jackets intended for the same use. Still not a big fan of the SV's style but it is now the only COLD WEATHER jacket I have hanging in our mud room getting daily use. And it is THE jacket I grab when I want to be warm and protected from the weather/elements on foot, on a horse or on a 4x4. Given the choices I have available that is saying a lot. It is still not the jacket I would take climbing. It is too heavy and not cut for climbing. Kappa and SL are light and cut to climb in. But the Fission SV is the one jacket I wish I had when I really need a warm jacket. Simply because it is the warmest most weather resistant synthetic I own.
